What is polyaluminium chloride (PAC)?

Polyaluminium chloride (PAC) is a widely used water treatment chemical. It has a wide range of PH adaptation and it is not easy to produce color or other side effects. After the use of poly aluminum chloride, the content of iron, manganese and other heavy metals in water is low, which has a little corrosive effect on the equipment.

What is polyaluminium chloride?

Polyaluminium chloride, also written as poly aluminium chloride, is an inorganic polymer coagulant used for water treatment. Take the first letter of words as abbreviation, it is refered to as PAC chemicals, can be considered as one of the best coagulants.

What is poly aluminum chloride used for?

Used in water treatment. With the properties of adsorption, aggregation and precipitation, Poly aluminum chloride is excellent coagulant in sewage treatment, industrial wastewater treatment, drinking water treatment, circulating water treatment, etc. Used in papermaking industry.

How to use polyaluminium chloride PAC coagulant in sewage treatment process?

Most industries need to use polyaluminium chloride PAC chemical in the sewage treatment process. The precipitation rate of PAC chemical is much faster and the precipitation effect is better. The use method of PAC coagulant is to dissolve it in a certain proportion and then add it to water.

Is polyaluminium chloride a safe coagulant?

Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.

Why is PAC used in water treatment?

PAC helps reduce the overall cost of water treatment by 15-30%. Compared to inorganic coagulants or flocculants, PAC is suited to broad water temperature including at low temperature. Water treated using PAC has fewer salts content and can be used for ion-exchange treatment. PAC contains lower corrosivity level and is easy to handle and operate.
